Testing and Surveillance Strategies

This research area will focus on better understanding the best mix of population level testing and surveillance strategies including symptomatic testing alongside passive, active, sentinel and syndromic surveillance approaches. Areas of interest include analysis of various types of tests, testing levels and targeting strategies.

Key Challenge Questions:

  1. What is the ideal testing strategy (including testing in people with and without symptoms and with and without known exposures) to mitigate and contain the pandemic, while minimizing unnecessary testing and inefficiencies?

    1. What is the relative efficacy and effectiveness of various testing approaches in relation to the mitigating the spread of COVID-19?

    2. What is the relative cost effectiveness of various testing approaches? 

    3. Given the level of vaccine uptake within the population at this time, how should testing strategies be adapted?

  2. What is the efficacy and effectiveness of testing outside of the context of known exposures (i.e., not in an outbreak and not for contacts of a case), considering time sensitivities, testing frequency, test turnaround time, and inter-laboratory variability?

    1. Where is the best yield for asymptomatic or surveillance testing in relation to mitigating spread? What is the best targeting strategy for asymptomatic testing and surveillance?

    2. What is the ideal frequency of testing outside of the context of known exposure to reduce the chance of outbreaks in high risk settings?
Please consider: All analyses should include consideration of population sub-groups, for example: sex, gender, and sexual orientation; people with high risk clinical characteristics; people with physical and/or mental health disabilities; Indigenous peoples and communities; immigrants and refugees; ethno-racial communities; Francophone communities; linguistic communities; religious/faith communities; homeless people; people living on a low income; people receiving social assistance; people using drugs; and people living in rural/remote or inner urban areas.
